Thyone nnisemiia (Stimpson). 
Verrill and Smith, 1873, p. 715, 503 (Stereo derma

Verrill records the taking of one specimen by

on bottom of clear sand. A half dozen col- 
lected by Clark at Crab Ledge, in August, 
1902, on sandy and gravelly bottom; also 
reported by this writer from Nantucket Shoals, 
off Gay Head, and in Narragansett Bay. 
Three specimens dredged by the Fish Hawk 
at Crab Ledge, July 23, 1907 (station 7838*); 
two others dredged in August, 1907, near sta- 
tion 7692*, at entrance of Vineyard Sound. 
(These specimens, according to Dr. Clark, 
“are remarkable for their elongated, slender 
form; stiff body wall; and comparatively few 
large pedicels. ”) A large individual, dredged 
August 15, 1908, at the western end of Vine- 
yard Sound, near Fish Hawk station 7719; 
several others on August 25, 1908, near Phala-

Vineyard Sound, Naushon Island, etc.; burrows 
deeply in the sand or gravel, near low- water 
mark. — Verrill. Woods Hole Plarbor, near 
entrance of the Eel Pond; abundant along 
shores of Buzzards Bay, about Naushon, 
Uncatena, and Nonamesset; less common on 
the sound side; occupying clean sand or soft 
mud, near, or at times above, low-water 
mark. — Clark. Vineyard Haven, near bridge; 
Tarpaulin Cove; head of Katama Bay, on 
western side. — R. C. Osburn. 
Eggs and sperms nearly ripe, April 24, 1898. — 
Mead. Probably breed during June and 
July. — Bumpus. “ Both species of Synapta 
breed during the spring and early summer. 
The sexual glands are well developed by the 
last of April, and individuals with ripe ova 
may be found well into August. About the 
last of June or early July seems to be the height 
of the breeding season.” — Clark. 
Leptosynapta roseola Verrill. 
Verrill and Smith, 1873, p. 716, 362; Mead, 
' 1898, p. 704; Clark, 1899, p. 21-31 ( Synapta 
roseola)', 1904, p. 571 ( Synapta roseola); 1905, 
p. 13 ( Synapta roseola). 
Naushon Island. — Verrill. Buzzards Bay, in 
the neighborhood of Woods Hole. — Clark. 
According to Verrill the occurrence and 
habits are similar to those of L. inhcerens. 
Clark, however, notes characteristic differ- 
ences of habitat, stating that L. roseola “occurs 
on rocky or gravelly shores under stones or 
among the pebbles, and never in pure sand or 
mud. ” He adds that he has never found this 
species in the Woods Hole region “except 
where there was sufficient iron present in the 
soil to give it a decidedly rusty color.” 
For breeding season see remarks under preceding 
species. 
Perhaps not distinct from the European T.fusus — Clark.
